A difference of just half a degree of global warming, from 1.5 to 2 degrees Celsius, would mean that an additional 5 million people worldwide will have the land where their homes are located be permanently submerged underwater, according to a new study published in the journal Environmental Research Letters.

The Uneven Gains of Energy Efficiency
On a rainy day in New Orleans, people file into a beige one-story building on Jefferson Davis Parkway to sign up for the Low-Income Heating and Energy Assistance Program (LIHEAP), a federal grant that helps people keep up with their utility bills. New Orleans has one of the highest energy burdens in the country, meaning that people must dedicate a large portion of their income to their monthly energy bills. This is due in part to it being one of the least energy-efficient cities in the country.
Wandering greenhouse gas
On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, it can also become trapped in the sea ice that forms in these coastal waters. As a result, the gas can be transported thousands of kilometres across the Arctic Ocean and released in a completely different region months later. This phenomenon is the subject of an article by researchers from the Alfred Wegener Institute, published in the current issue of the online journal Scientific Reports. Although this interaction between methane, ocean and ice has a significant influence on climate change, to date it has not been reflected in climate models.
NASA Powers on New Instrument Staring at the Sun
NASA has powered on its latest space payload to continue long-term measurements of the Sun's incoming energy.
80% cut in liver metastasis by restricting the blood vessels supplying it
Metastasis is the process whereby a tumour that grows in one organ breaks away from it and travels to another organ and colonises it. In the colonisation process it needs to create new blood vessels through which the cancer cells obtain the nutrients and oxygen they need to grow. This blood vessel formation process is called angiogenesis and is carried out by the endothelial cells. "Unlike normal endothelial cells and due to the signals, that reach them from the tumour cells, the cells that supply the tumours have increased growth and tend to move towards the metastatic mass to help it grow,” said Iker Badiola, member of the Signaling Lab research group in the Department of Cell Biology and Histology of the UPV/EHU’s Faculty of Medicine and Pharmacy.
